To make reading easier, this page is split up in two sections:
Miscellaneous characters - Every character or group of characters that cannot readily be placed on the student or adult subpages.
Dead Fast cast - In addition to the above, there is a handful of characters that are fiction even in the fiction of Monster High. So far, they are all part of the Dead Fast cast.
All characters within a section are listed alphabetically.
As Monster High is about teenagers, obviously it has to reserve a spot for celebrities to idolize. To fill that spot, a number of celebrity backgrounders occasionally show up.
